I have an 18 foot Bestway round pool, however, it doesn’t come outfitted with a skimmer of any kind. I had green algae but I successfully killed it all, scrubbed everything down, and it’s now white and on the bottom of the pool. The problem is... the vacuum it came with only does debris - the white mesh bag hooked up to a brush and water hose, that’s it. The pump is on the ground, not attached to the pool. I’ve tried everything short of breaking the bank. Advice please!
